We will have the following:
First, we can see that the following points belong to the line:
[tex]\begin{gathered} (0,4) \\ \\ and \\ \\ (2,0) \end{gathered}[/tex]
Now, we replace in the general equation of the line, that is:
[tex]\begin{gathered} y-4=(\frac{0-4}{2-0})(x-0)\Rightarrow y-4=-2x \\ \\ \Rightarrow y=-2x+4 \end{gathered}[/tex]
So, the equation will be:
[tex]y=-2x+4[/tex]
